> Where does ((char*)x)[1234] point to for unsigned int x=0?

It points to the 1234'th byte of your program's code, although usually
programs start at byte 4096.  More likely it points into the unmapped
page at the beginning of your program, so you'd get a segfault if you
tried to use it.

Remember, djgpp still uses segments - and your programs are *tiny*
mode.  You need a segment offset to get to memory outside your segment
(like dos memory, video, etc). (unless you use nearptrs, of course).
